In a post-cued letter identification task, participants were presented with 7-letter nonword target stimuli that were formed of a random string of consonants (DCMFPLR) or a pronounceable sequence of consonants and vowels (DAMOPUR). Targets were preceded by briefly presented pattern-masked primes that could be the same sequence of letters as the target, composed of seven different letters, or sh...

Recent research on the Roman alphabet has demonstrated that the magnitudes of masked repetition priming are equivalent for letter pairs that have similar visual features across cases (e.g., c-C) and for letter pairs with dissimilar features (e.g., g-G). Here, we examined whether priming of abstract letter representations occurs in an orthographic system, Arabic, in which the letters show an int...

standardizing persian alphabet letters in pcs, note books and cell phones is an important issue in persian writing. diversity of letters assigned to a given key as well as inappropriateness of the assigned letters to keys in relation to the frequency of letters are the most important issues for the iranians using persian keyboards. although the standard persian keyboard has been organized in a ...

background: letters to the editor provide an opportunity for readers to state their views about published articles. research on this issue has been mainly on western journals and there is no study on the iranian journals. the present study aimed to investigate this subject in iranian biomedical journals. materials and method: this was a bibliometric study. the databases of iran medex, medlib, a...

Theories of verbal rehearsal usually assume that whole words are being rehearsed. However, words consist of letter sequences, or syllables, or word onset-vowel-coda, amongst many other conceptualizations of word structure. A more general term is the 'grain size' of word units (Ziegler and Goswami, 2005). In the current study, a new method measured the quantitative percentage of correctly rememb...

For a rational number r such that 1<r≤2, an undirected r-power is word of the form xyx′, where x nonempty, x′ in {x,xR}, and we have |xyx′|/|xy|=r. The repetition threshold for k letters, denoted URT(k), infimum set all r-powers are avoidable on letters. We first demonstrate URT(3)=74. Then show URT(k)≥k−1k−2 k≥4. conjecture URT(k)=k−1k−2 k≥4, confirm this k∈{4,5,…,21}. then consider related pr...

Selection tasks in which simple stimuli (e.g. letters) are presented and a target stimulus has to be selected against one or more distractor stimuli are frequently used in the research on human action control. One important question in these settings is how distractor stimuli, competing with the target stimulus for a response, influence actions. The distractor-response binding paradigm can be u...

One of the most important steps in teaching English is teaching its alphabet to the learners. Implementing the best method will highly help teachers to achieve acceptable results in helping students to read better and faster. Two basic methods are frequently used by Iranian educators. Some start by the name of the letters and introduce the sounds that they symbolize later, while others are thos...
